Joseph W. Beyers

Chairman of the Board and Chief Executive Officer

IF YOU RETURN YOUR PROXY CARD WITHOUT
AN INDICATION OF HOW YOU WISH TO VOTE, YOUR SHARES WILL BE VOTED IN FAVOR OF THE RESTRUCTURING PROPOSAL AND EACH OF THE OTHER PROPOSALS.

THIS NOTICE, THE PROXY STATEMENT AND
OUR FORM OF PROXY CARD ARE AVAILABLE ON THE INTERNET AT:http://ir.inventergy.com/proxy-information.

Inventergy Global,
Inc. (the “Company”) has delivered printed versions of these materials by mail to holders of record and has
otherwise made these materials available on the internet in connection with the Company’s solicitation of proxies for use
at our Special Meeting of Stockholders (the “Special Meeting”), which will take place on [*], [*], 2017 at 10:00
a.m. Pacific Time, at the Company headquarters at 900 E. Hamilton Avenue, Suite 180, Campbell, California 95008, and any postponement(s)
or adjournment(s) thereof.

This proxy statement
gives you information on each of the proposals put forth by the board of directors of the Company (the “Board”)
so that you can make an informed decision. These materials were first sent or given to all stockholders of record entitled to vote
at the Special Meeting on or about [*], 2017.

In this proxy statement,
we refer to Inventergy Global, Inc. as the “Company,” “we,” “us” or “our” or similar
terminology.

What is included
in these materials?

If
you are a holder of record of our common stock, par value $0.001 per share (“Common Stock””), you will
have received a printed version of the proxy materials, which include:

·

This proxy statement for the Special Meeting; and

·

A proxy card along with voting instructions.

If
you are a beneficial owner (as described in more detail below) of shares of our Common Stock, you will have received a one-page
Notice of Internet Availability of Proxy Materials (the “Internet Availability Notice”) in the mail. By following
the instructions on the Internet Availability Notice, you will have access to this proxy statement for the Special Meeting.

If
you are a beneficial owner of shares of our Common Stock and requested printed versions of these materials by mail, you will receive
the proxy statement and the proxy card or voting instruction form for the Special Meeting.

Why did I receive a one-page notice
in the mail regarding the internet availability of proxy materials instead of a full set of proxy materials?

Pursuant
to rules adopted by the Securities and Exchange Commission (“SEC”), the Company has elected to provide access
to its proxy materials via the internet instead of mailing printed copies for the beneficial holders of our Common Stock. Accordingly,
the Company is sending an Internet Availability Notice to the Company’s beneficial stockholders. Most stockholders will not
receive printed copies of the proxy materials unless they request them. Instead, instructions on how to access the proxy materials
over the internet or to request a printed copy may be found with the Internet Availability Notice. All stockholders, including
holders of our Common Stock, will have the ability to access the proxy materials on the website referred to in the Internet
Availability Notice and all beneficial stockholders will have the ability to request to receive a printed set of the proxy materials.
Stockholders who have not received printed versions of the materials may request to receive the proxy materials in printed form
by telephone, mail, by logging on to http://www.proxyvote.com or electronically by email on an ongoing basis. The Company
encourages its stockholders to take advantage of the availability of the proxy materials on the internet to help reduce the environmental
impact of our annual and special meetings.

1

How can I get electronic access to the
proxy materials?

The
Internet Availability Notice will provide you with instructions regarding how to:

·

View the Company’s proxy materials for the Special Meeting on the Internet; and

·

Instruct the Company to send future proxy materials to you electronically by email.

Choosing to receive
future proxy materials by email will save the Company the cost of printing and mailing documents to you and will reduce the impact
of the Company’s annual and special meetings on the environment. If you choose to receive future proxy materials by email,
you will receive an email message next year with instructions containing a link to those materials. Your election to receive proxy
materials by email will remain in effect until you terminate it.

Who can vote at the Special Meeting
of stockholders?

Stockholders who owned
shares of our Common Stock on January 11, 2017 (the “Record Date”) may attend and vote at the Special Meeting.
There were 11,532,235 shares of Common Stock outstanding on the Record Date.

How many votes am I entitled to per
share?

Each share of Common
Stock entitles the holder thereof to one vote. If all of our stockholders vote their Common Stock as of the Record Date at the
Special Meeting there will be an aggregate of 11,532,235 votes cast at the Special Meeting.

What is the proxy card?

The proxy card enables
you to appoint Joseph W. Beyers, our Chief Executive Officer and Chairman of the Board, and/or John Niedermaier, our Chief Financial
Officer and Secretary, as your representative at the Special Meeting. By completing and returning the proxy card (or voting online
or by telephone, if permissible and as described herein), you are authorizing these persons to vote your shares at the Special
Meeting in accordance with your instructions on the proxy card. This way, your shares will be voted whether or not you attend the
Special Meeting. Even if you plan to attend the Special Meeting, it is strongly recommended that you complete and return your proxy
card before the Special Meeting date just in case your plans change. If a proposal comes up for vote at the Special Meeting that

What am I voting on?

to vote:

1.

To approve the assignment of the Company’s current patent portfolio, as contemplated under
the Restructuring Agreement (the “Restructuring Agreement”), dated as of December 22, 2016, by and between the
Company and the Subsidiaries of the Company, and DBD Crediting Funding LLC and CF DB EZ LLC, to a newly created special purpose
entity as described in the Restructuring Agreement, such entity the “SPE” (which is referred to as the “Restructuring
Proposal”);

2.

To amend Article IV of the Company’s Certificate of Incorporation, as amended (the “Certificate
of Incorporation”), to effect a reverse stock split (the “Reverse Split”) of the Company’s capital
stock at a ratio of between one-for-two and one-for-five, with such ratio to be determined at the sole discretion of the Board

of more than 20% of the Company’s issued and outstanding common stock pursuant to the Company’s financing in July 2016

How does the Board recommend that I
vote?

Our Board unanimously
recommends that the stockholders vote “FOR” the approval of the Restructuring Proposal, “FOR”
the approval of the Reverse Split Proposal and “FOR” the approval of the Nasdaq Proposal.

What is the difference between holding
shares as a stockholder of record and as a beneficial owner?

Most of our stockholders
hold their shares in an account at a brokerage firm, bank or other nominee holder, rather than holding share certificates in their
own name. As summarized below, there are some distinctions between shares held of record and those owned beneficially.

Stockholder of Record

If, on the Record Date,
your shares were registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you
are a “stockholder of record” who may vote at the Special Meeting, and we are sending these proxy materials directly
to you. As the stockholder of record, you have the right to direct the voting of your shares by returning the enclosed proxy card
to us, to vote on the internet at www.cstproxyvote.com or to vote in person at the Special Meeting. Whether or not you plan
to attend the Special Meeting, please complete, date and sign the enclosed proxy card to ensure that your vote is counted.

Beneficial Owner

If, on the Record Date,
your shares were held in an account at a brokerage firm or at a bank or other nominee holder, you are considered the beneficial
owner of shares held “in street name,” and these proxy materials are being forwarded to you by your broker or nominee
who is considered the stockholder of record for purposes of voting at the Special Meeting. As the beneficial owner, you have the
right to direct your broker on how to vote your shares and to attend the Special Meeting. However, since you are not the stockholder
of record, you may not vote these shares in person at the Special Meeting unless you receive a valid proxy from your brokerage
firm, bank or other nominee holder. To obtain a valid proxy, you must make a special request of your brokerage firm, bank or other
nominee holder. If you do not make this request, you can still vote by using the voting instruction card enclosed with this proxy
statement; however, you will not be able to vote in person at the Special Meeting.

If I am a holder of record of Common
Stock, how do I vote?

There are three ways
to vote:

(1) In
person.If you are a holder of record of our Common Stock, you may vote in person at the
Special Meeting. The Company will give you a ballot when you arrive.

(2) By
mail. As described above, all holders of record of our Common Stock will receive printed versions of the proxy materials, including
the proxy card. As such, you may vote by proxy by filling out the proxy card and sending it back in the envelope provided.

(3) Via
the internet. You may vote via the internet by following the instructions provided on your proxy card.

3

If I am a beneficial owner of shares
of our Common Stock held in street name, how do I vote?

(1) Via
the internet. You may vote via the internet by following the instructions provided by your brokerage firm, bank, broker-dealer
or other similar organization that holds your shares.

(2) Via
telephone. Using a touch-tone telephone, you may transmit your voting instructions to the number provided in the proxy statement.

(3) In
person.If you are a beneficial owner of shares of our Common Stock held in street name
and you wish to vote in person at the Special Meeting, you must obtain a legal proxy from the brokerage firm, bank, broker-dealer
or other similar organization that holds your shares. Please contact that organization for instructions regarding obtaining a legal
proxy.

(4) By
mail. If you request printed copies of the proxy materials by mail, you may vote by proxy by filling out the vote instruction
form and sending it back in the envelope provided by your brokerage firm, bank, broker-dealer or other similar organization that
holds your shares.

If I am a beneficial owner of shares
of our Common Stock, how do I request a paper copy of the proxy materials?

There are four ways
to request a paper copy of proxy materials:

•

Global, Inc., 900 E. Hamilton Avenue, Suite 180, Campbell, California 95008, Attn: Secretary.

•

By telephone. You may obtain a paper copy of the proxy materials by calling 1-800-579-1639
or the Company at 408-389-3510.

•

By Email: You may obtain a paper copy of the proxy materials by email at sendmaterial@proxyvote.com.

for a paper copy as instructed above on or before [*], 2017 to facilitate timely delivery.

What does it mean if I receive more
than one proxy card?

You may have multiple
accounts at the transfer agent and/or with brokerage firms. Please sign and return all proxy cards to ensure that all of your shares
are voted.

What if I change my mind after I return
my proxy?

You may revoke your
proxy and change your vote at any time before the polls close at the Special Meeting. You may do this by:

·

sending a written notice to John Niedermaier, our corporate Secretary, stating that you would like
to revoke your proxy of a particular date;

·

signing another proxy card with a later date and returning it before the polls close at the Special
Meeting; or

·

attending the Special Meeting and voting in person.

4

Please note, however,
that if your shares are held of record by a brokerage firm, bank or other nominee, you must instruct your broker, bank or other
nominee that you wish to change your vote by following the procedures on the voting form provided to you by the broker, bank or
other nominee. If your shares are held in street name, and you wish to attend and vote at the Special Meeting, you must bring to
the Special Meeting a legal proxy from the broker, bank or other nominee holding your shares, confirming your beneficial ownership
of the shares and giving you the right to vote your shares.

Will my shares be voted if I do not
sign and return my proxy card?

If your shares are
held in street name or in your name and you do not sign and return your proxy card, your shares will not be voted unless you vote
in person at the Special Meeting.

How are votes counted?

You may vote “for,”
“against,” or “abstain” on each of the proposals being placed before our stockholders. Abstentions, but
not broker non-votes, will be counted for the purpose of determining whether a quorum is present at the Special Meeting.

Broker non-votes occur
on a matter when a broker is not permitted to vote on that matter without instructions from the beneficial owner and instructions
are not given. These matters are referred to as “non-routine” matters. The Restructuring Proposal, the Reverse Split
Proposal and the Nasdaq Proposal are “non-routine” matters. Thus, in tabulating the voting result for these three proposals,
shares that constitute broker non-votes are not considered votes cast on those proposals.

How many shares must be present or represented
to conduct business at the Special Meeting?

The quorum requirement
for holding the Special Meeting and transacting business is that holders of a majority of the Common Stock outstanding as of the
Record Date must be present in person or represented by proxy. Abstentions are counted for the purpose of determining the presence
of a quorum. However, broker non-votes are not counted for the purpose of determining the presence of a quorum. In order to meet
the quorum requirement for holding the Special Meeting and transacting business, holders of a total of 5,766,118 shares must be
present in person or represented by proxy at the Special Meeting.

How many votes are required to approve
the Restructuring Proposal?

The affirmative vote
of a majority of the issued and outstanding shares of Common Stock entitled to vote at the Special Meeting is required to approve
the Restructuring Proposal.

How many votes are required to approve
the Reverse Split Proposal?

The affirmative vote
of a majority of the issued and outstanding shares of Common Stock entitled to vote at the Special Meeting is required for approval
of the Reverse Split Proposal

How many votes are required to approve
the Nasdaq Proposal?

The affirmative vote
of a majority of the votes cast at the Special Meeting by the holders of Common Stock is required for approval of the Nasdaq Proposal.

What happens if I don’t indicate
how to vote my proxy?

If you just sign your
proxy card without providing further instructions, your shares will be voted “FOR” the Restructuring Proposal,
“FOR” the Reverse Split Proposal and “FOR” the Nasdaq Proposal.

Is my vote kept confidential?

Proxies, ballots and
voting tabulations identifying stockholders are kept confidential and will not be disclosed except as may be necessary to meet
legal requirements.

5

Where do I find the voting results of
the Special Meeting?

We will announce preliminary
voting results at the Special Meeting. The final voting results will be tallied by the inspector of election at the Special Meeting
and then published in the Company’s Current Report on Form 8-K, which the Company is required to file with the SEC within
four business days following the Special Meeting.

Who can help answer my questions?

You can contact our
Secretary, John Niedermaier, by telephone at (408) 389-3510, by email at CFO@inventergy.com, or by sending a letter to Mr. Niedermaier
at the Company’s offices of the Company at 900 E. Hamilton Avenue #180, Campbell, CA 95008 with any questions about proposals

Stockholders
who hold their shares of Common Stock in “street name,” meaning that a broker or other nominee is the record holder
of their Common Stock, must either direct the record holder of their shares to vote their shares or obtain a proxy or voting instruction
from the record holder to vote their shares at the Special Meeting.

Expenses

The cost of preparing,
assembling, printing and mailing this proxy statement and the accompanying form of proxy, and the cost of soliciting proxies relating
to the Special Meeting, will be borne by the Company. Some banks and brokers have customers who beneficially own Common Stock listed
of record in the names of nominees. We intend to request banks and brokers to solicit such customers and will reimburse them for
their reasonable out-of-pocket expenses for such solicitations. If any additional solicitation of the holders of our outstanding
shares of Common Stock is deemed necessary, we (through our directors and officers) anticipate making such solicitation directly.
The solicitation of proxies by mail may be supplemented by telephone, mail and personal solicitation by officers, directors and
other employees of the Company, but no additional compensation will be paid to such individuals.

Revocability of Proxies

PROPOSAL 1

THE RESTRUCTURING PROPOSAL

Restructuring Agreement

On December 22, 2016,
the Inventergy Global, Inc. (the “Parent”), Inventergy Inc., a wholly-owned subsidiary of Parent (the “Owner”),
and the other subsidiaries of the Parent (together with the Parent and Owner, the “Company”) entered into a
Restructuring Agreement (the “Restructuring Agreement”) with DBD Creidt Funding LLC and CF DB EZ LLC, affiliates
of Fortress Investment Group, LLC (collectively referred to as “Fortress”) to amend that certain Amended and
Restated Revenue Sharing and Note Purchase Agreement (the “Revenue Sharing and Note Purchase Agreement”), which
was originally entered into by the Parent, Owner and Fortress on October 1, 2014.

Pursuant to the Restructuring
Agreement, Fortress was given the sole discretion to, either directly or by direction to the Company, make any and all decisions
relating to the Company’s patents and patent monetization activities (excluding future acquired patents related to Inventergy
Innovations, LLC, a subsidiary of Parent, and related monetization activities) (such patents that are subject to the Restructuring
Agreement, the “Patents”), including the right to license, sell or sue unauthorized users of the Patents (the
“Monetization Activities”).

In addition, the Restructuring
Agreement modifies the revenue share provided for in the Revenue Sharing and Note Purchase Agreement such that all proceeds from
the Monetization Activities will be applied as follows: (i) first, to pay for certain third party expenses incurred by the Company,
Fortress or third party brokers in relation to the Monetization Activities, (ii) second, to pay up to $2.2 million of the Company’s
outstanding principal debt to Nokia Corporation (“Nokia”) to the extent any Monetization Activity is directly
attributable to the Company’s Nokia patent portfolio, and the Company has previously paid all accrued and outstanding interest
to Nokia, (iii) third, if a Monetization Activity triggers a payment with respect to a retained interest owed to a prior owner
under agreements with Panasonic Corporation or Huawei Technologies Co., Ltd., payment will be made to such prior owner, as required,
(iv) fourth, to Fortress until the Note Obligations under the Revenue Sharing and Note Purchase Agreement is paid in full, (v)
fifth, to Fortress until Fortress has received (x) reimbursement of any amounts advanced by Fortress pursuant to the Restructuring
Agreement plus 20% annual interest on such advances plus (y) $30.5 million less any amounts paid to Fortress for the Note Obligations
under the Revenue Sharing and Note Purchase Agreement after December 22, 2016, and (vi) sixth, after all of the foregoing payment
obligations are satisfied, 70% to Fortress and 30% to the Company. The Company will continue to be fully responsible for all expenses
related to the maintenance, prosecution and enforcement of the Patents, until the completion of the SPE structure as described
below, and shall be fully responsible to pay any interest or other charges relating to the debt owed to Nokia and to make principal
payments as and when due to the extent Monetization Activities have not generated amounts to make such principal payments.

The Restructuring Agreement
contemplates that the parties will work towards obtaining stockholder approval and third party consent to the assignment of the
Patents to a newly created special purpose entity, or SPE. The Company has until March 31, 2017 to complete that process. Upon
obtaining stockholder approval and third party consent, the Company will assign the Patents to the SPE. The SPE will be managed
by Fortress, and the economic arrangements provided for under the Restructuring Agreement will be reflected in the governing documents
for the SPE and/or in contractual arrangements between the SPE and the Company.

The Restructuring Agreement
defers any amortization payments on the notes held by Fortress until April 1, 2017, and also suspends the Company’s minimum
liquidity covenant, each to permit time for the Company to effect the SPE structure described above. Upon the SPE structure becoming
effective, the Company’s note obligations to Fortress will be extinguished, the Company will be relieved of any scheduled
amortization (instead, payments to Fortress will only be required out of Monetization Revenues), the liquidity covenant will no
longer apply, and the Company will be relieved from any further responsibility to maintain the Patents, retroactive to December
22, 2016.

10

The Restructuring Agreement
is subject to certain events of default, including, among other things, liquidation or dissolution, change of control, bankruptcy,
the Company’s failure to make payments pursuant to the terms of the Restructuring Agreement, the Company’s failure
to secure necessary consents to permit completion of the SPE structure or the Company’s failure to perform or observe certain
covenants. Upon the occurrence of an event of default, Fortress may proceed to protect and enforce its rights through seeking the
Company’s specific performance of any covenant or condition, as set forth in the Restructuring Agreement, or may declare
the remaining unpaid balance owed under the Revenue Sharing and Note Purchase Agreement, as amended, and any other amounts owed
pursuant to the Restructuring Agreement to be immediately due and payable.

The terms of the Restructuring
Agreement are complex and only briefly summarized above. For further information regarding the Restructuring Agreement and the
transactions contemplated thereby, please refer to our Current Report on Form 8-K filed with the SEC on December 29, 2016. The
discussion herein is qualified in its entirety by reference to the complete text of the Restructuring Agreement.

Reasons for the Restructuring Proposal

The Restructuring Proposal,
once approved and implemented, will eliminate the requirement for the Company to make monthly principal and interest payments on
the notes and to pay the notes at maturity or upon acceleration, will eliminate the liquidity covenant, and will replace the note
obligations and current revenue share with comprehensive revenue share through the SPE structure. Fortress, through its control
of the SPE, will continue to have sole discretion over the management of the monetization efforts for the Patents and will have
full discretion over whether and to what extent to fund such monetization efforts. The Company will be relieved of the ongoing
expense of maintaining the Patents, retroactive to December 22, 2016, which will be the sole responsibility of the SPE (subject
to Fortress’s sole discretion over whether to maintain or abandon any such Patents).

The Company is required
under the Restructuring Agreement to use its best efforts to secure the necessary stockholder approval and third party consent
to reflect the SPE structure described above, and has prepared this proxy statement to seek such stockholder approval.

Potential Disadvantages of the Restructuring
Proposal

The Restructuring Agreement
requires the Company to assign the Patents to an SPE, and Fortress will have full, direct control over the Patents under this structure.
The Company’s sole remaining interest in the Patents will be the contractual right to 30% of monetization revenues, subject
to the prior distributions provided under, and other terms and conditions specified in, the Restructuring Agreement. Regardless
of the success of the monetization of the Patents, the Company will have no control over, ownership of, or recourse to, the Patents.

Effect of the Restructuring Proposal
on Stockholders

The Restructuring Proposal
will have no dilutive effects on the Company’s stockholders as the Company will not be issuing any securities in relation
to its entry into the Restructuring Agreement. However, as mentioned in the preceding paragraph, the Restructuring Agreement will
require the Company to assign the Patents to an SPE. This will result in a significant reduction of assets on the Company’s
balance sheet.

Consequence of Failure to Obtain Stockholder
Approval of the Restructuring Proposal

In the event the Company’s
stockholders do not approve the Restructuring Proposal, the Company will default on the Restructuring Agreement and a Non-Recourse
Event of Default under the Note Obligation and Revenue Share Agreement will occur. In this situation, all of the note and revenue
share amounts payable to Fortress under the Restructuring Agreement will then become due and payable to Fortress and Fortress will
have the ability to take control of and dispose of the patent assets to pay the amounts due to them.

Required Vote

The affirmative
vote of a majority of the issued and outstanding shares of common stock entitled to vote at the Special Meeting is required
to approve the Restructuring Proposal. Abstentions and broker non-votes are considered present for purposes of establishing a
quorum but will have the effect of a vote against the Restructuring Proposal.

Recommendation
of the Board

THE BOARD UNANIMOUSLY
RECOMMENDS A VOTE “FOR” THE RESTRUCTURING PROPOSAL.

PROPOSAL 2

THE
Reverse split proposal

Introduction

On December 19, 2016, the Board acted unanimously
to adopt the Reverse Split Proposal to amend Article IV of our Certificate of Incorporation to enable a potential Reverse Split
of our Common Stock at a ratio of between one-for-two and one-for-five, with such ratio to be determined at the sole discretion
of the Board and with such Reverse Split to be effected at such time and date, if at all, as determined by the Board in its sole
discretion. The Board is now asking you to approve this Reverse Split Proposal.

Effecting the Reverse
Split requires that Article IV of our certificate of incorporation (the “Certificate of Incorporation”) be amended
to include a reference to the Reverse Split. If approved, the Reverse Split will be effective upon the filing of a Certificate
of Amendment to the Certificate of Incorporation, in the form attached to this proxy statement as Annex A (the “Certificate
of Amendment”), with the Secretary of State of Delaware, with such filing to occur, if at all, at the sole discretion
of the Board.

The intention of the Board in obtaining
approval for the authority to effect a Reverse Split would be to increase the stock price of our Common Stock sufficiently above
the $1.00 minimum bid price requirement for continued listing on The Nasdaq Capital Market (“Nasdaq”) if necessary
in the future. The Board, in its sole discretion, can elect to abandon the Reverse Split in its entirety at any time.

One principal effect
of the Reverse Split would be to decrease the number of authorized and outstanding shares of our Common Stock (including the proportionate
number of shares of Common Stock issuable upon conversion of our Series C Convertible Preferred Stock, par value $0.001 per share
(the “Series C Preferred Stock”), Series D Convertible Preferred Stock, par value $0.001 per share (the “Series
D Preferred Stock”), and Series E Convertible Preferred Stock, par value $0.001 per share (the “Series E Preferred
Stock,” and collectively with the Series C Preferred Stock and the Series D Preferred Stock, the “Preferred
Stock”), as described below. Except for de minimus adjustments that may result from the treatment of fractional shares
as described below, the Reverse Split will not have any dilutive effect on our stockholders (whether such stockholders hold Common
Stock or Preferred Stock) since each stockholder would hold the same percentage of our Common Stock or Preferred Stock (in hand
or on an as converted basis) outstanding immediately following the Reverse Split as such stockholder held immediately prior to
the Reverse Split. The relative voting and other rights that accompany the shares would not be affected by the Reverse Split.

The table below sets
forth the number of shares of our Common Stock outstanding before and after the Reverse Split based on 11,532.235 shares of Common
Stock outstanding as of the Record Date. The table below also sets forth the number of shares of Common Stock issuable upon conversion
of the Preferred Stock before and after the Reverse Split based on 3,335 shares, 186,367 shares and 1,496,262 shares outstanding,
respectively, as of the Record Date.

The Reverse Split will
not have any dilutive effect on our stockholders as the proportion of shares owned by our stockholders relative to the number of
shares authorized for issuance will remain the same.

The total number of
authorized shares of Common Stock will be reduced from 100,000,000 shares to between 50,000,000 shares in the event of a one-for-two
reverse split and 20,000,000 shares in the event of a one-for-five reverse split. The number of shares of Preferred Stock authorized
will be reduced from a present 10,000,000 shares to between 5,000,000 shares in the event of a one-for-two reverse split and 2,000,000
shares in the event of a one-for-five reverse split.

The Reverse Split is
not part of a broader plan to take us private.

Reasons for the Reverse Split; Nasdaq
Requirements for Continued Listing

The
Board’s primary objective in proposing a potential Reverse Split is to raise the per share trading price of our Common
Stock. Our Common Stock currently trades on Nasdaq under the symbol “INVT.” In order to maintain our listing on
Nasdaq we may be required to effect the Reverse Split so that our listed shares maintain a minimum bid price per share of
at least $1.00.

On November 21,
2016, the Company received notice from The Nasdaq Stock Market indicating that, because the closing bid price for our Common Stock
had fallen below $1.00 per share for 30 consecutive business days, the Company no longer complied with the minimum bid price requirement
for continued listing on Nasdaq under Rule 5550(a)(2) of Nasdaq Marketplace Rules. Pursuant to Nasdaq Marketplace Rule 5810(c)(3)(A),
the Company was provided an initial compliance period of 180 calendar days, or until May 22, 2017, to regain compliance with the
minimum bid price requirement. For that initial compliance period, to regain compliance, the closing bid price of our Common Stock
must have met or exceeded $1.00 per share for a minimum of 10 consecutive business days prior to May 22, 2017. If the Company does
not regain compliance by that date, it has the option to request a six-month extension until December 22, 2017. If this extension
request is needed, the Board believes that the authority by the Board to effect the Reverse Split will materially increase the
likelihood of the Company being granted such an extension if requested.

Our Board concluded
that the liquidity and marketability of our Common Stock will be adversely affected if it is not listed on a national securities
exchange as investors can find it more difficult to dispose of, or to obtain accurate quotations as to the market value of, our
Common Stock. Our Board believes that current and prospective investors will view an investment in our Common Stock more favorably
if our Common Stock remains quoted on Nasdaq.

Our Board also believes
that the Reverse Split and any resulting increase in the per share price of our Common Stock will enhance the acceptability and
marketability of our Common Stock to the financial community and investing public. Many institutional investors have policies prohibiting
them from holding lower-priced stocks in their portfolios, which reduces the number of potential buyers of our Common Stock, although
we have not been told by them that is the reason for not investing in our Common Stock. Additionally, analysts at many brokerage
firms are reluctant to recommend lower-priced stocks to their clients or monitor the activity of lower-priced stocks. Brokerage
houses frequently have internal practices and policies that discourage individual brokers from dealing in lower-priced stocks.
Further, because brokers’ commissions on lower-priced stock generally represent a higher percentage of the stock price than
commissions on higher priced stock, investors in lower-priced stocks pay transaction costs which are a higher percentage of their
total share value, which may limit the willingness of individual investors and institutions to purchase our Common Stock.

We cannot assure you
that the Reverse Split will have any of the desired effects described above. More specifically, we cannot assure you that after
the Reverse Split the market price of our Common Stock will increase proportionately to reflect the ratio for the Reverse Split,
that the market price of our Common Stock will not decrease to its pre-split level, that our market capitalization will be equal
to the market capitalization before the Reverse Split, or that we will be able to maintain our listing on Nasdaq.

14

Potential Disadvantages of the Reverse
Split

As noted above, the
principal purpose of the Reverse Split would be to help increase the per share market price of our Common Stock by up to factor
of five. We cannot assure you, however, that the Reverse Split will accomplish this objective for any meaningful period of time.
While we expect that the reduction in the number of outstanding shares of Common Stock will increase the market price of our Common
Stock, we cannot assure you that the Reverse Split will increase the market price of our Common Stock by a multiple equal to the
number of pre-split shares, or result in any permanent increase in the market price of our Common Stock, which is dependent upon
many factors, including our business and financial performance, general market conditions and prospects for future success. If
the per share market price does not increase proportionately as a result of the Reverse Split, then the value of our Company as
measured by our stock capitalization will be reduced, perhaps significantly.

The number of shares
held by each individual holder of Common Stock would be reduced if the Reverse Split is implemented. This will increase the number
of stockholders who hold less than a “round lot,” or 100 shares. Typically, the transaction costs to stockholders selling
“odd lots” are higher on a per share basis. Consequently, the Reverse Split could increase the transaction costs to
existing holders of Common Stock in the event they wish to sell all or a portion of their position.

Although our Board
believes that the decrease in the number of shares of our Common Stock outstanding as a consequence of the Reverse Split and the
anticipated increase in the market price of our Common Stock could encourage interest in our Common Stock and possibly promote
greater liquidity for our stockholders, such liquidity could also be adversely affected by the reduced number of shares outstanding
after the Reverse Split.

Effecting the Reverse Split

Upon receipt of stockholder
approval for the Reverse Split Proposal, if our Board concludes that it is in the best interests of our Company and our stockholders
to effect the Reverse Split, the Certificate of Amendment will be filed with the Secretary of State of Delaware. The actual timing
of the filing of the Certificate of Amendment with the Secretary of State of Delaware to effect the Reverse Split will be determined
by our Board. In addition, if for any reason our Board deems it advisable to do so, the Reverse Split may be abandoned at any time
prior to the filing of the Certificate of Amendment, without further action by our stockholders. In addition, our Board may deem
it advisable to effect the Reverse Split even if the price of our Common Stock is above $1.00 at the time the Reverse Split is
to be effected. The Reverse Split will be effective as of the date of filing with the Secretary of State of the State of Delaware
(the “Effective Time”).

Upon the filing of
the Certificate of Amendment, without further action on our part or our stockholders, the outstanding shares of Common Stock and
Preferred Stock held by stockholders of record as of the Effective Time would be converted into a lesser number of shares of Common
Stock and Preferred Stock based on a Reverse Split ratio as determined by the Board. For example, if you presently hold 1,500 shares
of our Common Stock, you would hold 750 shares of our Common Stock following the Reverse Split if the ratio is one-for-two or you
would hold 300 shares of our Common Stock if the ratio is one-for-five.

Effect on Outstanding Shares, Options
and Certain Other Securities

If the Reverse Split
is implemented, the number of shares our Common Stock and Preferred Stock owned by each stockholder will be reduced in the same
proportion as the reduction in the total number of shares outstanding, such that the percentage of our Common Stock and Preferred
Stock owned by each stockholder will remain unchanged except for any de minimus change resulting from rounding up to the nearest
number of whole shares so that we are not obligated to issue cash in lieu of any fractional shares that such stockholder would
have received as a result of the Reverse Split. The number of shares of our Common Stock and Preferred Stock that may be purchased
upon exercise of outstanding options or other securities convertible into, or exercisable or exchangeable for, shares of our Common
Stock, and the exercise or conversion prices for these securities, will also be ratably adjusted in accordance with their terms
as of the Effective Time.

Effect on Registration

Our Common Stock is
currently registered under the Securities Act of 1933, as amended, and we are subject to the periodic reporting and other requirements
of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The proposed Reverse Split will not
affect the registration of our Common Stock.

Fractional Shares; Exchange of Stock
Certificates

Our Board does not
currently intend to issue fractional shares in connection with the Reverse Split. Therefore, we do not expect to issue certificates
representing fractional shares. In lieu of any fractional shares, we will issue to stockholders of record who would otherwise hold
a fractional share because the number of shares of Common Stock or Preferred Stock they hold of record before the Reverse Split
is not evenly divisible by the Reverse Split ratio that number of shares of Common Stock or Preferred Stock as rounded up to the
nearest whole share. For example, if a stockholder holds 150.25 shares of Common Stock following the Reverse Split, that stockholder
will receive certificate representing 151 shares of Common Stock. No stockholders will receive cash in lieu of fractional shares.

As of the Record Date,
we had 159 holders of record of our Common Stock (although we have significantly more beneficial holders) and 11 holders of record
of our Preferred Stock. We do not expect the Reverse Split and the rounding up of fractional shares to whole shares to result in
a significant reduction in the number of record holders. We presently do not intend to seek any change in our status as a reporting
company for federal securities law purposes, either before or after the Reverse Split.

On or after the Effective
Time, we will mail a letter of transmittal to each stockholder. Each stockholder will be able to obtain a certificate evidencing
his, her or its post-Reverse Split shares only by sending the exchange agent (who will be the Company’s transfer agent) the
stockholder’s old stock certificate(s), together with the properly executed and completed letter of transmittal and such
evidence of ownership of the shares as we may require. Stockholders will not receive certificates for post-Reverse Split shares
unless and until their old certificates are surrendered. Stockholders should not forward their certificates to the exchange agent
until they receive the letter of transmittal, and they should only send in their certificates with the letter of transmittal. The
exchange agent will send each stockholder, if elected in the letter of transmittal, a new stock certificate after receipt of that
stockholder’s properly completed letter of transmittal and old stock certificate(s). A stockholder that surrenders his, her
or its old stock certificate(s) but does not elect to receive a new stock certificate in the letter of transmittal will be deemed
to have requested to hold that stockholder’s shares electronically in book-entry form with our transfer agent.

Certain of our registered
holders of Common Stock hold some or all of their shares electronically in book-entry form with our transfer agent. These stockholders
do not have stock certificates evidencing their ownership of our Common Stock. They are, however, provided with a statement reflecting
the number of shares registered in their accounts. If a stockholder holds registered shares in book-entry form with our transfer
agent, the stockholder may return a properly executed and completed letter of transmittal.

Stockholders who hold
shares in street name through a nominee (such as a bank or broker) will be treated in the same manner as stockholders whose shares
are registered in their names, and nominees will be instructed to effect the Reverse Split for their beneficial holders. However,
nominees may have different procedures and stockholders holding shares in street name should contact their nominees.

16

Stockholders will not
have to pay any service charges in connection with the exchange of their certificates.

Authorized Shares

If and when our Board
elects to effect the Reverse Split, the Certificate of Amendment will concurrently therewith reduce the authorized number of shares
of our Common Stock from 100,000,000 to between 50,000,000 and 20,000,000 and the authorized number of shares of our Preferred
Stock from 10,000,000 to between 5,000,000 and 2,000,000. Thus, following the Reverse Split, the proportion of shares owned by
our stockholders relative to the number of shares authorized for issuance will remain constant as the authorized shares available
for issuance will be reduced in equal proportion to the reduction in shares outstanding.

In accordance with
our Certificate of Incorporation and Delaware law, our stockholders do not have any preemptive rights to purchase or subscribe
for any of our unissued or treasury shares.

Anti-Takeover and Dilutive Effects

The authorized Common
Stock and Preferred stock will not be diluted as a result of the transaction. The Common Stock and Preferred Stock that is authorized
but unissued provide the Board with flexibility to effect among other transactions, public or private financings, acquisitions,
stock dividends, stock splits and the granting of equity incentive awards. However, these authorized but unissued shares may also
be used by our Board, consistent with and subject to its fiduciary duties, to deter future attempts to gain control of us or make
such actions more expensive and less desirable. The Certificate of Amendment would continue to give our Board authority to issue
additional shares from time to time without delay or further action by the stockholders except as may be required by applicable
law or regulations. The Certificate of Amendment is not being recommended in response to any specific effort of which we are aware
to obtain control of us, nor does our Board have any present intent to use the authorized but unissued Common Stock or Preferred
Stock to impede a takeover attempt. There are no plans or proposals to adopt other provisions or enter into any arrangements that
have material anti-takeover effects.

Accounting Consequences

As of the Effective
Time, the stated capital attributable to Common Stock and Preferred Stock on our balance sheet will be reduced proportionately
based on the Reverse Split ratio (including a retroactive adjustment of prior periods), and the additional paid-in capital account
will be credited with the amount by which the stated capital is reduced. Reported per share net income or loss will be higher because
there will be fewer shares of our Common Stock and Preferred Stock outstanding.

Federal Income Tax Consequences

The following summary
describes certain material U.S. federal income tax consequences of the Reverse Split to holders of our Common Stock and Preferred
Stock. This summary addresses the tax consequences only to a beneficial owner of our Common Stock and Preferred Stock that is a
citizen or individual resident of the United States, a corporation organized in or under the laws of the United States or any state
thereof or the District of Columbia or otherwise subject to U.S. federal income taxation on a net income basis in respect of our
Common Stock or Preferred Stock (a “U.S. holder”). This summary does not address all of the tax consequences
that may be relevant to any particular stockholder, including tax considerations that arise from rules of general application to
all taxpayers or to certain classes of taxpayers or that are generally assumed to be known by investors. This summary also does
not address the tax consequences to persons who may be subject to special treatment under U.S. federal income tax law or persons
that do not hold our Common Stock or Preferred Stock as “capital assets” (generally, property held for investment).
This summary is based on the provisions of the Internal Revenue Code of 1986, as amended, U.S. Treasury regulations, administrative
rulings and judicial authority, all as in effect as of the date hereof. Subsequent developments in U.S. federal income tax law,
including changes in law or differing interpretations, which may be applied retroactively, could have a material effect on the
U.S. federal income tax consequences of the Reverse Split.

17

If a partnership (or
other entity classified as a partnership for U.S. federal income tax purposes) is the beneficial owner of our Common Stock or Preferred
Stock, the U.S. federal income tax treatment of a partner in the partnership will generally depend on the status of the partner
and the activities of the partnership. Partnerships that hold our Common Stock or Preferred Stock, and partners in such partnerships,
should consult their own tax advisors regarding the U.S. federal income tax consequences of the Reverse Split.

Each stockholder
should consult his, her or its own tax advisor regarding the U.S. federal, state, local and foreign income and other tax consequences
of the Reverse Split.

The Reverse Split should
be treated as a recapitalization for U.S. federal income tax purposes. Therefore, no gain or loss should be recognized by a U.S.
holder upon the Reverse Split. Accordingly, the aggregate tax basis in the Common Stock or Preferred Stock received pursuant to
the Reverse Split should equal the aggregate tax basis in the Common Stock or Preferred Stock surrendered and the holding period
for the Common Stock or Preferred Stock received should include the holding period for the Common Stock or Preferred Stock surrendered.

Text of Proposed Certificate of Amendment;
Effectiveness

The text of the proposed
Certificate of Amendment is set forth in Annex A to this proxy statement. If and when effected by our Board, the
Certificate of Amendment will become effective upon its filing with the Secretary of State of Delaware.

Required Vote

Approval of the Reverse
Split Proposal requires the affirmative vote of a majority of the issued and outstanding shares of Common Stock entitled to vote
at the Special Meeting. Abstentions are considered present for purposes of establishing a quorum but will have the effect of a
vote against the Reverse Split Proposal.

On July 21, 2016, the
Company entered into a securities purchase agreement (the “PurchaseAgreement”) with certain institutional
accredited investors (the “Investors”). Pursuant to the Purchase Agreement, the Company sold to the Investors
in a private placement 3,000 shares of Series E Convertible Preferred Stock (“Series E Preferred Stock”), each
having a stated value of $1,000, for aggregate gross proceeds of $3.0 million (the “Financing”). Pursuant to
the Certificate of Designation for the Series E Preferred Stock (the “Certificate of Designation”), the Series
E Preferred Stock is immediately convertible into 1,496,262 shares of Common Stock, subject to certain beneficial ownership limitations,
at an initial conversion price equal to $2.005 per share, subject to adjustment. After January 25, 2017, the conversion price will
be equal to the lesser of (a) the conversion price then in effect or (b) 65% of the volume weighted average price of Common Stock
for ten consecutive days prior to the applicable conversion date. The Certificate of Designation contains provisions providing
for an adjustment in the conversion price upon the occurrence of certain events, including stock splits, stock dividends, dilutive
equity issuances and fundamental transactions. However, in no event may the conversion price be lower than $0.25 per share. The
Company may redeem some or all of the Series E Preferred Stock for cash as follows: (i) on or prior to September 25, 2016, in an
amount equal to 126% of the aggregate stated value then outstanding, (ii) after September 25, 2016 and on or prior to January 25,
2017, in an amount equal to 144% of the aggregate stated value then outstanding and (iii) after January 25, 2017, in an amount
equal to 150% (and later amended to 165%) of the aggregate stated value then outstanding.

Each Investor also
received a common stock purchase warrant (the “Warrants”) to purchase up to a number of shares of Common Stock
equal to 85% of such Investor’s subscription amount divided by $2.005. The Warrants are exercisable for a term of five years
commencing six months after the closing of the transaction at a cash exercise price of $2.005 per share. In the event that the
shares underlying the Warrants are not subject to a registration statement at the time of exercise, the Warrants may be exercised
on a cashless basis after six months from the issuance date. The Warrants also contain provisions providing for an adjustment in
the exercise price upon the occurrence of certain events, including stock splits, stock dividends, dilutive equity issuances (so
long as the Series E Preferred Stock is outstanding) and fundamental transactions. Notwithstanding the forgoing, until the Company
obtains Stockholder Approval (as defined below), the conversion of the Series E Preferred Stock is limited to 19.99% of the outstanding
Common Stock immediately prior to the date of the Financing.

The Purchase
Agreement requires the Company to hold a special meeting of stockholders to seek the approval of the holders of its Common
Stock for the issuance of the number of shares of Common Stock issuable upon the conversion of the Series E Preferred Stock
in excess of 19.99% of the outstanding Common Stock immediately prior to the date of the Financing (the
“StockholderApproval”). Until the Company obtains the Stockholder Approval, the conversion of the
Series E Preferred Stock is limited to 19.99% of the outstanding Common Stock (or 970,000 shares of Common Stock) immediately
prior to the date of the Financing. Additionally, until the Series E Preferred Stock is no longer outstanding, the
Investors may participate in future offerings for up to 50% of the amount of such offerings.

The terms of the Purchase
Agreement, the Certificate of Designation and the Warrants are complex and only briefly summarized above. For further information
regarding these agreements and the Financing, please refer to our Current Report on Form 8-K filed with the SEC on July 22, 2016.
The discussion herein is qualified in its entirety by reference to such filed transaction documents.

Why the Company Needs Stockholder Approval

We are seeking the
Stockholder Approval in order to comply with Nasdaq Listing Rules 5635(d). Under Nasdaq Listing Rule 5635(d), stockholder approval
is required for a transaction other than a public offering involving the sale, issuance or potential issuance by an issuer of Common
Stock (or securities convertible into or exercisable for Common Stock) at a price that is less than the greater of book or market
value of the stock if the number of shares of Common Stock to be issued is or may be equal to 20% or more of the Common Stock,
or 20% or more of the voting power, outstanding before the issuance. Since the conversion price of the Series E Preferred Stock
under the Certificate of Designation was lower than the market price of our Common Stock on the date of issuance of the Series
E Preferred Stock, the Company requires the Stockholder Approval to issue, pursuant to the Financing, 20% or more of our outstanding
Common Stock as calculated immediately prior to the date of the Financing.

19

Effect of Proposal on Current Stockholders

If the Nasdaq Proposal
is adopted, based on an initial conversion price per share of the Series E Preferred Stock of $2.005, up to a maximum of 1,496,262
shares of Common Stock would be issuable upon conversion of the Series E Preferred Stock, representing up to 13.0% of the shares
of our Common Stock outstanding on the date hereof (and representing 11.5% of the shares of our Common Stock outstanding assuming
the shares of Series E Preferred Stock are converted into an aggregate of 1,496,262 shares of Common Stock on the date hereof).
Furthermore, after January 25, 2017, the conversion price will become equal to the lesser of (a) the conversion price then in effect
or (b) 65% of the volume weighted average price of the Company’s common stock for ten consecutive days prior to the applicable
conversion date (but no lower than $0.25). If the Nasdaq Proposal is adopted and subsequently the conversion price is significantly
below $2.005 per share (the closing price of our common stock on January 4, 2016 was $0.77), substantially more than 1,496,262
shares of common stock would be issuable upon conversion of the Series E Preferred Stock. The issuance of such shares could result
in significant dilution to our stockholders, and could substantially reduce our stockholders’ percentage interest in the
voting power of the Company. In addition, the sale or any resale of the Common Stock issued upon conversion of the Series E Preferred
Stock could cause the market price of our Common Stock to decline further.

Notwithstanding the
foregoing, the Company currently intends to redeem the Series E Preferred Stock with proceeds from future patent monetization revenue
or the sale of equity or debt securities. Pursuant to the terms of the Series E Preferred Stock, the Company, at its option, may
redeem some or all of the Series E Preferred Stock for cash as follows: (i) on or prior to September 25, 2016, in an amount equal
to 126% of the aggregate stated value of the Series E Preferred Stock then outstanding (which is equal to $3,780,000), (ii) after
September 25, 2016 and on or prior to January 25, 2017, in an amount equal to 144% of the aggregate stated value then outstanding
(which is equal to $4,320,000) and (iii) after January 25, 2017, in an amount equal to 165% of the aggregate stated value then
outstanding (which is equal to $4,950,000).

Consequence of a Failure to Provide
Stockholder Approval

If our stockholders
do not approve the Nasdaq Proposal, we will have the right to issue shares up to 19.9% of the Company’s issued and outstanding
Common Stock upon conversion of the Series E Preferred Stock, pursuant to the Financing, without stockholder approval. In the event
that Stockholder Approval is not obtained and deemed effective on or before January 26, 2017, from that date until Stockholder
Approval is obtained, the Company cannot (i) enter into any transaction or series of transactions that constitutes a dilutive issuance
as defined in the Certificate of Designation if such issuance would cause the exercise price of the Warrants to be reduced or (ii)
be a party to any solicitations, negotiations or discussions with regard to the foregoing.

Required Vote

The approval of this
proposal will be made upon the affirmative vote of the majority of shares cast on the proposal. Abstentions and broker non-votes
will have no effect on the outcome of this proposal.

Recommendation of the Board

THE BOARD UNANIMOUSLY
RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE NASDAQ PROPOSAL.

OTHER INFORMATION

Principal Stockholders

The following table
sets forth the total number of shares beneficially owned, as of January [*], 2017, by:

•

each person known by us at that date to be the beneficial owner of more than 5% of the outstanding
shares of our common stock based solely on such person’s filings with the Securities and Exchange Commission;

•

each of our officers and directors as of such date; and

•

each of our officers and directors as of such date, as a group.

As used in the table
below, the term beneficial ownership with respect to the common stock consists of sole or shared voting power (which includes the
power to vote, or to direct the voting of shares of the common stock) or sole or shared investment power (which include the power
to dispose, or direct the disposition of, the shares of common stock). Beneficial ownership is determined according to the rules
of the SEC, which generally provide that a person has beneficial ownership of a security if the security holder possesses sole
or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable
within 60 days. Unless otherwise indicated, we believe that all persons named in the table below have sole voting and investment
power with respect to all shares of common stock beneficially owned by them.

As of January [*],
2017, there were 11,532,235 shares of common stock, 5 shares of Series C preferred stock, 369 shares of Series D preferred stock
and 3,000 shares of Series E preferred stock outstanding.

the purposes of amending the Certificate of Incorporation, as amended (the “Certificate of Incorporation”) of Inventergy
Global, Inc. (the “Corporation”), a corporation organized and existing under and by virtue of the General Corporation
Law of the State of Delaware, does hereby certify that:
